Answer:
22.5%
Step-by-step explanation:
let the standard deviation for market portfolio = σₙ
Also let the standard deviation for fully diversified portfolio = σₓ
<u>To calculate fully diversified portfolio</u>
fully diversified portfolio has <em>σₓ = βσₙ</em>
From the given question beta (β) = 1.25
Also standard deviation for market portfolio (σₙ) = 18% = 0.18
<em>From the equation above, σₓ = βσₙ </em>= 1.25×0.18 = 0.225
= 22.5% (converting to percentage)

The two closest integers that 300 sqrt is 17 and 18
Answer:
The answer is 23 years.
Step-by-step explanation:
We will use the formula :

Here P = 220
r = 3%
A = 400
Putting these values in the formula we get,


Taking log on both sides,
ln(1.03)t=ln 2

t=23.44 or rounding to nearest, t=23 years
The graph of the function can be shown as below.
Answer: 
Step-by-step explanation:
We know that:

Where "d" is distance, "r" is rate and "t" is time.
Solved for the time "t":

The first step is to convert the distance from miles to feet.
Since
, we get:

Knowing that:

We can substitute values into
in order to find the time in seconds:

Since:

The time in minutes is:
